Title: System synchronising receiver clock signals to information telegram - has window circuit generating time slots and control circuits shortening them at start of telegram
Inventor: STEIN HERMANN
IPC: H04L7/08
Filed: 1977-11-30
Abstract: The clock signals are synchronised with the beginning and/or end of an information telegram received from a transmitter, from which consecutive timing signals can be derived. At least one timing signal is transmitted with a different spacing in time in order to mark the beginning or end of the telegram. The receiver has a window circuit (3-11) which generates consecutive time slots following each other at the specified spacing. The receiver generates clock signals simultaneously with, or at a multiple of the spacing after, each timing signal outside the time slot. A control circuit (13, 23, 27, 31) reduces the duration of the generated time slot, starting from a maximum duration, at the beginning of each telegram.

Title: Glass lamp bulbs with pumping tubes - are formed using sequence of heating and drawing operations converting single tube into two lamp bulbs
Inventor: BROECHELER HERBERT
IPC: C03B23/11
Filed: 1978-04-27
Abstract: The cylindrical lamp bulbs are made of hard- or heat resistant- glass, esp. for halogen lamps, starting from a glass tube employed to make at least two lamp bulbs. The glass tube is subjected to a sequence of local heating operations with drawing to make two constrictions in the tube. The space between the constrictions is then heated and the tube drawn, to make a long narrow zone forming a pump tube for two lamp bulbs. During the drawing operations, calibrating tools are used and air is blown through the glass tube so desired bore dias. are obtd. when the process is complete. Both the lamp tubes and their pump tubes have exact bore dias.

Inventor: WEINLICH TILMAN LUDWIG DIPL IN
IPC: E06B3/67
Filed: 1978-09-05
Abstract: Two glass panes (I) are sepd. from each other by a relatively large gap, e.g. of ca. 100 mm; and one or more thin coated plastic foils which reflect infrared light (IR) are located between panes (I).

Title: Valve control for four-stroke otto and Disel engines - connects single valve in head with butterfly valve selectively connecting with inlet and exhaust
Inventor: GOEBEL KARL-HEINZ
IPC: F01L1/28
Filed: 1979-03-22
Abstract: The inlet and outlet valve system of four stroke engines operating on the Otto or Diesel cycle is designed to reduce the number of moving valves. In comparison with prior art engine design a single valve (3) is located at the top of the engine combustion chamber (2). A secondary butterfly valve plate (9) is pivoted off centre (10) between inlet and exhaust ducts (7, 8). When the piston moves down on the induction cycle the main valve opens and suction causes the butterfly plate to tilt allowing inlet flow (7). On the exhaust cycle the high pressure on the underside of the plate causes it to tilt to open the exhaust port, due to the larger area on the exhaust side.

The electric motor, which can rotate in either direction, drives the needle, which is attached to a disc, either directly or via gears. At least one measurement value, pref. zero, is adjustable absolutely. The motor drive may be controlled via the contact between the moving indicator needle and slip contacts on its path of motion and connected in the motor current circuit.
Patent DE-2921145-A1 (DE)
Title: Lead-copper-selenium alloy - is free of tin and suitable for cladding purposes
Inventor: REINERT MAX
IPC: C22C11/04
Filed: 1979-05-25
Abstract: The corrosion resistant alloy has the compsn. Cu 0.03-0.15%, balance Pb and contains 0.005-0.05% Se (0.01-0.025%). The addn. of Se produces a fine-grained structure. The alloy is suitable for cladding, for example steel for use in the production of chem. apparatus. The addn. of Se produces a fine-grained structure which reduces the tendency to hot cracking as a result of tension stresses during cooling of the Pb alloy layer. The grain refinement is obtd. by the formation of finely dispersed Pb selenide coupled with a fine distribution of Cu. An improvement in corrosion resistance is achieved by a further addn. of Pd 0.005- 0.05% and passivation is produced by adding :10-400 g/t Ni. The alloy is applied to the substrate by casting or build-up welding.

Title: Guidance system for projectiles - measures azimuth and distance ensuring high steering accuracy towards moving ground target
Inventor: SCHNAEBELE WERNER DIPL ING
IPC: F41G9/00
Filed: 1979-08-10
Abstract: A projectile (3) is fired on a ballistic track (1) in the direction of a chosen target (5), from a ground station having a location device (4). With the help of the command steering, the projectile (3) can be diverted from the original ballistic path (1) and steered onto the target distance (15) on the reference azimuth. The further follow up of the projectile corresp. to the target movement, is computed by the difference measuring method. The antenna of the locating device (4) is chosen as the reference point, and the deviations of the projectile (3) relative to the target (5) are controlled against zero. The track or path, on which the projectile (3) is steered into the target, can be visualized as an imaginary sighting line which, dependent on the position of the projectile, its elevation and the target distance, exhibits various geometric shapes, and is determined by a calculator. The projectile (3) can be controlled to match target deviations in the azimuth, dependent of the geometric shape of the sighting lines (6,7,8).
